3 rd Workshop on

Description of the Workshop

The workshop on Knowledge and Reasoning in Practical Dialogue System will focus on the role and use of ontologies to develop flexible, adaptive, user-friendly, and enjoyable multi-modal dialogue systems. We encourage both papers presenting successful use of ontologies as well papers on potential drawbacks (or challenges).

This is the third workshop on Knowledge and Reasoning in Practical Dialogue System. The first workshop was organised at IJCAI in Stockholm in 1999 IJCAI in Stockholm in 1999. The second workshop was held at IJCAI 2001 in Seattle and continued along the same lines.

Topics addressed in this workshop include, but are not limited to:

  • Techniques for extending dialogue systems' intelligence through rich semantic modelling as realized by building large ontologies, including how to improve responses with the aid of ontologies.
  • Representations of ontologies; XML, RDF, metatagging; database formats.
  • Investigations on multimodal interaction, e.g. what properties are important for an acceptance of multimodal interaction from the users.
  • Development and maintenance of shared knowledge sources and especially issues on the dynamic nature of the information sources demanding means for automatic update, and the fact that some knowledge sources are shared.
  • Generality vs specificity of the ontology: applicability to various applications.
  • Techniques for automatic construction of ontologies.
  • Techniques for automatic, semi-automatic or dynamic updates of ontologies for new tasks and domains.
  • Considerations on how to merge several ontologies on the one hand or automatically extend ontologies on the other.
  • Dialogue systems that utilise a domain ontology and ontology-based document processing.
  • Extending ontology-based Q&A systems to allow for connected dialogue.
  • Architectures for systems combining dialogue management and document processing.
  • Investigations of how a domain ontology can be used by the different modules in a dialogue system.

Who should attend

This workshop aims at bringing together researchers and practitioners that work on the development of communication models that support robust and efficient interaction in natural language, both for commercial dialogue systems and in basic research.

It should be of interest also for anyone studying dialogue and multimodal interfaces and how to coordinate different information sources. This involves theoretical as well as practical research, e.g. empirical evaluations of usability, formalization of dialogue phenomena and development of intelligent interfaces for various applications, not excluding such areas as Robotics.

The workshop will encourage the participation of both system builders and theoretically oriented researchers, thus creating a forum for discussion across vocational and disciplinary borders. While taking practical applications and implemented dialogue systems as our point of departure, we emphasize the potential contributions of theoretical and empirical research: applications are the best testbeds for evaluating the usefulness and originality of theories and ideas. There is a certain lack of communication between theorists and system builders, and the workshop aims at creating an atmosphere that allows for a productive interaction between these two groups.

Workshop format

The workshop will be kept small, with a maximum of 40 participants. Preference will be given to active participants selected on the basis of their submitted papers. According to IJCAI rules, all workshop attendees must register for the main conference.

Each paper will be given ample time for discussion, more than what is customary at a conference. As said above, we encourage contributions of a critical or comparative nature that provide fuel for discussion. We also invite people to share their experiences of implementing and coordinating knowledge modules in their dialogue systems, and integrating dialogue components to other applications.
